Application January 24, 1936, Serial No. 60,688

1 Claim.

This invention relates to clamps especially adapted for releasably securing bolting machine socks, and has for the primary object the provision of a device of this character which may be easily and quickly applied or removed while the bolting machine is in operation and will be selfadjusting when applied to provide eflicient securing of a sock in place either to a bolting machine or to an outlet spout and will prevent accidental detachment of the sock.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of our invention, reference is to be had to the following description and accompanying drawing, in which- Figure l is a fragmentary View, partly inv section, showing the securing in place of socks to: a bolting machine by clamps constructed in accordance with our invention.

Figure 2 is a plan view illustrating the clamp.

Figure 3 is a side elevation illustrating the clamp.

Figure 4 is a perspective view illustrating a spring to be used in connection with the clamp.

Referring in detail to the drawing, the numeral l indicates a split band or ring for encircling a sock 2 after the application of the latter to the outlet 3 of a bolting machine or may be employed for securing the sock to the outlet spout 4. The split band or ring is constructed of resilient material having a natural tendency to contract so as to provide a desired gripping action upon the sock. The end 5 of the split band or ring is first bent upon itself to form an eye 6 and a finger piece I. The other end 8 of the band or ring is bent upon itself to form a guide eye 9 and then bent upon itself to form substantially parallel portions I0 and H connected, as shown at I2. The portion ll extends through the eye 6 and the portion l0 extends through the eye 9 and is then bent to form a finger piece I3 paralleling the finger piece I. By moving the finger piece l3 in the direction of the finger piece I the split band or ring I will be expanded so that it may be easily applied or removed from the sock.

To provide further contraction to the split ring or band a spring M is provided, the ends of which are offset, as shown at I5, to be engaged with the finger pieces, as shown by. dot and dash lines in Figure 2. The spring will act to urge the split band or ring into its fullest contracted position. The contraction of the split band or ring is limited by the eyes 6 and 9 and the members i0 and II extending through said eyes.

A device of the character described can be cheaply manufactured and sold at a low cost and will permit a sock to be secured to a bolting machine With quickness and ease during the operation of the bolting machine.

Having described the invention, we claim:

A clamp comprising a self contractible split ring, one end of said ring being extended and bent upon itself to form an eye and a finger piece, the other end of said ring being extended and bent to form an eye and substantially parallel connected portions with one portion extending through one eye and the other portion extending through the other eye and bent to form a finger piece paralleling the first-named finger piece, and a spring member having offset ends to engage with the finger pieces.
